This presentation is part of LearnItFirst's SQL Server 2012: A Comprehensive Introduction course. The video that contains this presentation can be watched here: https://www.youtube.com/watch?v=FzayiGi97bc The concept of ETL is one of the more important concepts that will be covered in the last couple chapters of this course. Even if you are not working with ETL today and now, chances are high that at some point you will be asked to. This video will explain the scenario in which a business has several different databases, and how to make it all fit together. Highlights from this slideshow: - What is Microsoft's ETL tool? - What enables a business to use so many different databases? - What different options do you have for building a dashboard? - Needs of the organization versus the requirements of the vendor

Process

SQL Server 2012 Integration
Services (SSIS) is Microsoft’s ETL
tool
– Extract, Transform, and Load

3. p. 33

Most businesses have data in more
than one format
– How does one business happen to use so
many different databases?

Let’s walk through a likely scenario
and see how this happens:
– 2001: The “AdventureWorks” company
launches a web store to complement its
brick-and-mortar stores
• ASP-based website
• SQL Server 2000 backend
• Customers are encouraged to phone questions in or
to send an email

5. p. 55

Things change...
– 2001: Launch with SQL 2000
– 2003: AdventureWorks buys a competitor
• Competitor used a PHP/MySQL ticketing system
• AW mgmt chooses to adopt this system for customer
ticketing rather than build/buy an alternative

more “stuff”:
• A PHP/MySQL project management system is
installed

– 2012: Executives want a B.I. solution
• You name it, they want it
• But...
– there’s no budget for software purchases...

18. p. 1818

No budget for new software = more
opportunities for you!
– You decide:
• ... to create a relational OLAP data warehouse to store all the
company’s historic data in a unified way
• ... to create a multidimensional database with multiple cubes (to
facilitate fast browsing of analytics)
• ... to install Excel 2013 on all CxO and management machines, and
to teach them how to build pivot tables and pivot charts
• ... to investigate Reporting Services as a way to build internal web
dashboards and subscription-based reporting
– On-the-job experience, here we come!

19. p. 1919

The company data is all “loosely
connected”
– A customer makes a small order via the website
– The same customer submits a “Help!” ticket
– Customer rep. has to make an order for a
replacement part
– Sales person takes customer to an entertainment
event
– Customer now makes a large order
– Key question: how did we acquire this customer?

Integration Services is your ETL tool
1. You Extract the data from the source to a
staging area
• Optional, but typically an MS SQL Server relational
database
2. You make any changes to the data (a.k.a. a
Transformation)
• Either in motion or in the staging area
3. You Load the data into the relational data
warehouse
4. You process the cube(s)
– SSIS is your “one stop shop” for all of this!

21. p. 2121
21
Your final step is to build a
dashboard
– Reporting Services or PowerPivot?
– Power View or Excel?
– SharePoint or email?
– On-demand or subscription-based?

22. p. 2222

Your dashboard is a hit!
